Which Candidates Mispronounced 'Nuclear' at Tonight's GOP Debate?

CNN's Western Republican presidential debate, held earlier tonight in Las Vegas, was quite a doozy. Of course, the highlight was Mitt Romney and Rick Perry's knock-down, drag-out fight over illegal immigration.

But that wasn't the only good part! Take for instance the point at which candidates were asked about the nuclear waste repository inside Nevada's Yucca Mountain. Would they remember to say "nuclear," or go with "nucular" and fall into the George W. Bush Memorial Pit of Mispronounced Despair? Find out by watching the video above (and feel free to use the comments to grade each candidate).
